RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

The Smith Chart™

Dr. Cynthia Furse (note Smith Chart earrings in her photo), a Professor of Electromagnetics at the University of Utah's Department of Electrical Engineering, has produced a very nice video series that covers a wide range of topics and techniques on the venerable Smith Chart. The ten videos begin with an introduction, progress through reflection coefficients, shorts and opens, impedance matching, a slot line example, and finally a summary.

Dr. Furse rose to worldwide fame about a decade ago a least partially based on the colorful handmade quit she created with a Smith Chart pattern; it is an exquisite example of juxtapositioning the traditional with the contemporary. Of course holding at least 13 patents and conducting research in bio-electromagnetics, antennas, wireless communication, electrical fault location, electrical properties of sea ice, and engineering education outreach helped as well.

Dr. Furse has many RF and microwave instructional videos on YouTube. She is also an avid outdoorswoman and craftswoman who loves horses... like my daughter, Sally.
